How eluvial process determines the difference in colour of soil layers
Natural EnvironmentsDecoding Soil Colors: How “Washing Away” Creates Earth’s Palette Ever stopped to really look at soil? I mean, beyond just seeing “dirt”? You might be surprised to find a whole spectrum of colors staring back at you. These aren’t just random hues; they’re clues, telling a story about what’s happening beneath our feet. And one
What models are available to estimate effect of surface water on groundwater quality?
Earth ScienceAsked by: Willie Russell What is surface water modeling? Surface water models are used to simulate surface water conditions and to assess surface water availability. How do models contribute to water quality management? Modeling can be used to assess (predict) future water quality situations resulting from different management strategies. For example, assessing the improvement in
What is a typical value of the Péclet number for internal waves?
Earth ScienceAsked by: Joshua Starboard What are internal waves in the ocean? Internal waves are the undersea equivalent of surface waves you see at the beach. They have a vital role in transferring heat, energy, and momentum in the ocean. The turbulence they create when they break helps move nutrient-laden water to the coastlines while moving
Why does the annual temperature range get bigger where latitude is higher?
Earth ScienceAsked by: Joshua Starboard Why are there larger annual temperature changes at higher latitudes? At higher latitudes, the angle of solar radiation is smaller, causing energy to be spread over a larger area of the surface and cooler temperatures. How does latitude affect annual temperature range? There is a relationship between latitude and temperature around
How can I tell if a rock is really petrified wood?
Earth ScienceAsked by: Brent Bakos Keep an eye out for little bits of sap or sap-like colors like red (often strong reds), orange, and tan around the smooth parts. Smooth sections are often 3 to 5 inches (7.6 to 12.7 cm) in length. If the specimen has no bark but looks and feels like wood, it’s
Possible Effects of a Nuclear Reactor Breach in the Mediterranean
Earth ScienceAsked by: Brent Bakos What happens if Zaporizhzhia blows? According to experts, if shelling hit the nuclear waste stored at the Zaporizhzhia plant, it could cause a major leak. “If missile strikes hit the nuclear waste storage, then [nuclear] pollution could spread through air and water,” said Ozharovsky. What are the potential consequences of a
